the sun is in the center of the solar system,it is the energy source for life in earth.The sun is made from hydrogen and helium these burn up.it formed approximately 4.6 billion years ago,it is about 330 thousand times bigger than earth.
The Sun produces a solar wind which contains charged particles such as electrons and protons. They escape the Sun’s intense gravity because of their high kinetic energy and the high temperature of the Sun’s corona.The Sun generates huge amounts of energy by combining hydrogen nuclei into helium. This process is called nuclear fusion.
